TO ALL WHOM. 1T MAY GONCERN. y i

Be it known that I, JOSEPH STONE., of Ghicagmin the county of Cook, and Stato of Illinois,'ha`ve invented a new and useful Improvement' in Machines for Welding Iron andvI do hereby declare fand make known that the following is a full, clear, and exact description of the same, reference being hadto theaccompanying draw ings, and the letters and'iigurcs marked'thcroon, which form part of this specification.` i

The principle of my said invention consists in-so constructing a machine for welding ironfthat` two welding hammers, one operating vertically and ou`e Operating horizontally, shall strike alternately upon an anvil suitably arranged and Veimstructed-.with lreference thereto said anvil also having a sliding movement away from and towards said hammers,-thc former movement to permit the bars of iron -to be properly arranged upon the said anvil without stopping the machine, and the latter movement to bring the sumennder the action of thosaid l hammers, substantially as hereinafter described.V Myinventionrfurther consistsin the employment, in connection with said hammers and anvil, of springs and draw-hooks, or'theirequivalents, for' the purpose, respectively,

oi' holding the harto be welded alternately beneath and opposite said hammers, and away from the angle in the anvil to prevent tbe formation of a seam or flange upon'the corner of the bar, substantially ashel'einafterset forth;l

To enable those skilled in the art to understand how to coilstructrand use 'my said invention, I willnot;

Figure 1 is aplan or top view of my invention.'

Figure 2 a side elevation of the same.

Figure ila vertical section thereof, at the line :z: in rig. 1 and `Figure 4 is an endview of .the same. i i A Similar letters of referencez therdiiferent. figures denote the' sameparts-ef myinvention. i

A represents a suitable frame, uppn which the operating parts oi the `machineiare supported B a curvedl shaft which holds `the vertical hammer C, as shown, ls'o thatby an oscillating movement of the said shaft,by

.proceed to describe the same with particularity; making reference in so do'ng'to theaforesaid drawings, in which-- .means of the arms F G,'and wheel H, which latter is iixed'upon the shaft I, the proper verticalstrolre is given` upon t-h'e anvil as hereinafter mentioned. The whole machine is .also operated by the revolution of the said shaftv; to which motion is imparted in.` any suitable manner. Thelziorirontal hammer is suitably attached upon inn oscillating shaft, J', to which is attached the lever Jfwhich is operated-upon bymeans ,of the camP,"upon Vthe''snidjsh'aft I, as shown, so as to impart or give the desired horizontal stroke. lThese 'tvvhammers areso operated upon as to strike alternately, the forwardmovement being given to `the hammer D, whilel the upward movement is given -tothc hammer C. These hammers are made adjustable in then-holder by menus of set-screws, as shown. The anvil is/constructed with an angle, soas to present resisting faces to :the strokes of b oth hammers, as shown, and lies in-the proper position with respect tofthe aforesaid hammers, while the barsparo being welded, but recedes back toallow another bar to he adjusted properly thereupon, without'stopping the motion of the hammers, which would benecessarywere the anvil stationary, remaining in said last-mentioned position long enough for the attendant to place thebaigfwhen it returns to theproper position to s ubiect said' bar to the action of the hammers. Thisreciprocating movement is eie'cted .by means of the arms e, attached to the anvil ns shown, acted uponby a suitable ca'm, as hereinafter described, being properlyvti'medto accomplish the desired results. The said armee c areconnected by acrOSsJJar at their rear ends, upon which is arranged a roller marked O, whichis operated upon toV give s'aid movements by the cam N, upon theshaft M,`which is .revolved by the shaft I by means of -thegeanwheels K L,as shown inig. 3, the receding movement'being eccted i by the spring E',` und the forward movement bythe pressure of said cam. S Sirepresent hooks n'hichoperatc draw Vthe bars 'to be `welded beneatlrthe vertical hammer to receive the vertical blovv, but release the saine .o

allow it 4to rest upon the vertical-face of the anvil to receive the horizontal stroke, the springs s .s1 operatingin like manner to hold the har up free from the anviljco receive saidhorizontal stroke, while they readily yield so as to allow the bnr'to rest upon the horizontallace ofthe anvil to receive the vertical blowns aforesaid. These hooks S Snare so constructed that thcirlengths may be adjusted by'means of the set-screws a, as shownfundthe y anvil E has un adjustment, edected by moansof the set-serew fr- T represents a shaft or rod, having'its supports in 'the sides of the machine, upon which is fixed a lever,;R, whose lower end is suitably attached-to the ends oi` Vsaid springs a c, while its uppcr end is operated upon by a. cam, Q, upon the shaft I. This am Q operates to t l erase draw the said hooks up against the iron barato be welded, and the spring V operates upon the rear ends of said hooks, 'to release them as desired.

The aforesaid machine is constructed, and proportioned, and arranged in its various parts so as to operate in the following described manner.: When motionis communicated to thc driving-shaft I, assuming 'che anvil to be ont from beneath the hammers, ready to receive the bars for welding, the vertical and horizontal hammers commence their alternate strokes ,as aforesaid. The bars of iron which are to b'c velded together, having been properly arranged upon the anvil, it advances beneaththesaid hammers. Just as the vertical hammer is to descend upon the bal-tho hooks S S' seize the bars anddraw them fairly and wholly beneath the 'face of the descending hammer, and -as soon as the blow is given the said hooks recede, and the springs s raise the bars up to receive the blot.' from the-horizontal hammer. When'a .suitable number of blon's are vvgiven, sutlicicnt to weld-the bar, the anvil rec'edes, the bar removed, the next bar placed, and the operation is repeated. By varying the proportions orsiae of the machine,'and using hammers with 'various faces, bars of any size or shape may v be welded by this machine.

Having described the nature, construction, and operation of my invention, I will now proceed to specify what I claim, and desire to' secure by Letters-Patent 1. In combination withl the alternating hammers C D, the sliding anvil E, when arrangedand operating substantially as and for the purpose set forth. v

2. In combination with the vertical hammer C, and the anvil- E, constructed substantially as described, I claim the arrangement of the hooks S S, or their equivalents, substantially` as set forth, operating as and for the purposes speciiied and shown.

3. I claim, in combination wit'n the anvil E, constructed as described, and the horizontol hammer D, the employment of the springs sa, or their equivalent, arranged and operating as and for the purposes sot forth.
